Secondary Market TFNs

The FCC prohibits the sale or brokerage of NANP toll-free numbers (TFNs), that is, telephone numbers within area codes 800, 888, 877, 866, 855, 844, and 833. The policy does not apply to specific TFNs that were originally issued as part of the Somos toll-free number auction on December 20, 2019.
